Senior Software Engineer

Senior Software Engineer, Enterprise AI PlatformOpenArt is an AI storytelling and visual creation platform used by millions of creators worldwide. We're building the next generation of creative tools powered by cutting-edge AI — enabling anyone to create videos, visuals, characters, and stories with unprecedented speed and imagination.We believe the future of creativity is AI-native, and we're shaping that future.Why Join OpenArtBrand-new function, real mandate — enterprise and team customers are one of our biggest growth levers, and most of the infrastructure behind them hasn't been built yet. You'll be the first engineer on it.Small team, massive surface area — senior engineers own whole systems, not slices.Real scale, real stakes — OpenArt serves millions of creators, and enterprise deals will close (or not) on what you ship.Founder-led engineering culture — both founders are technical and deeply involved in product and architecture.AI-native product — you'll decide how cutting-edge models get packaged, governed, and sold to teams and enterprises.High ownership, low process — we value judgment, clarity, and speed over bureaucracy.About the RoleWe're hiring a senior engineer to build the product and infrastructure that lets OpenArt serve teams and enterprises, not just individual creators. That spans the full surface: workspaces and team management, roles and permissions, usage-based billing and procurement-friendly invoicing, audit logs, and the security posture — SSO, data controls, compliance groundwork — that larger customers expect before they'll sign.This is a full-stack role in the enterprise function. You'll move between customer-facing product (admin consoles, billing UI, workspace settings) and the backend and infrastructure underneath it (access control, usage metering, payment integrations, hardening our systems for enterprise-grade reliability and security). You'll work directly with the founders to figure out, in real time, what "enterprise-ready" needs to mean for an AI-native creative platform — and then build it.What You'll DoDesign and build core enterprise primitives: organizations/workspaces, roles and permissions (RBAC), SSO/SAML, and audit loggingBuild usage-based billing, invoicing, and payment infrastructure that supports both self-serve and enterprise procurement (e.g. Stripe)Harden platform security and reliability to the bar enterprise customers expect — access control, data isolation, and groundwork for compliance certifications (e.g. SOC 2)Design scalable backend architectures and APIs that support multi-tenant, team-based usage patternsBuild clean, polished frontend experiences (React/Next.js) for admin, billing, and workspace managementPartner directly with founders, sales, and customers to turn deal-blocking requirements into shipped platform featuresMake pragmatic build-vs-buy calls on infrastructure (billing providers, auth providers, compliance tooling) and clearly communicate the trade-offsDefine OpenArt's enterprise engineering practices as the function's first hire, and help shape the team that grows around itWhat We're Looking ForCore Requirements5+ years of full-stack engineering experience shipping and owning production systems at scaleStrong system design and data modeling skills — comfortable reasoning about APIs, permission models, multi-tenancy, and data isolationHands-on experience with infrastructure and platform work: cloud architecture, observability, scaling, or reliability engineeringA strong AI-assisted coding practice — you use tools like Claude Code, Codex, or Cursor as a core part of how you build, and have real opinions about what makes them work wellProduct sense for B2B — you know what makes an admin console feel trustworthy to an IT buyer and a workspace feel effortless for a teamStrong communication skills — you can sit in a customer security review or a sales call, then translate what you heard into clear technical trade-offs for non-technical teammatesNice to HaveExperience with payments or billing systems (e.g. Stripe): subscriptions, usage-based billing, invoicing, disputesExperience with security or compliance work: SSO/SAML, RBAC, audit logging, SOC 2 / GDPR groundworkExperience selling to or building for enterprise customers, including procurement and security-review cyclesStartup experience, or ownership of a large product surface from 0 to 1Compensation$500k+ total compensation including base salary, bonus, equityEquity - meaningful ownership in what you buildHigh autonomy, high growth environmentWork SetupBay Area preferred (hybrid available)Visa sponsorship availableWhat Success Looks Like in 3–6 MonthsWorkspaces, roles, and permissions are live in production and used by paying teamsEnterprise billing — usage metering, invoicing, procurement-friendly payments — is shipped and stableAt least one enterprise deal has closed on the strength of features you built (e.g. SSO, audit logs)SOC 2 groundwork is underway, and you can walk a customer's security team through our posture with confidenceYou're setting the direction for enterprise engineering — pushing ideas, not waiting for specsIf you want to build the platform that turns a consumer AI product into an enterprise business — and own it from day one — we'd love to talk.
